Jason Isaacs

Last TV role: "Awake" (2012) Why we want him back: In addition to playing the vile Lucius Malfoy in the blockbuster "Harry Potter" films, Isaacs proved his knack for carrying quality dramas as a complex leading man in two underappreciated series: NBC's "Awake" and Showtime's "Brotherhood." Suggested role: Showtime's straight-to-series, classy horror show "Penny Dreadful" is looking for just the right actors to fill an ensemble of iconic characters including Dr. Frankenstein, Dorian Gray, Dracula, Van Helsing and more. We know one Brit who would be a perfect fit for anything you ask of him. -- Geoff Berkshire, Zap2it
